It's not a lot of volume if you just process the numbers of HK, but if you bundle all the countries going through economical/political turmoil, the volumes suddenly aren't that bad at all. In fact, this is only the start. I expect that the situation will be much worse in the forthcoming years, which will only drive Bitcoin adoption to the next level in these countries.
Are you referring to a specific figure? Would you mind sharing it? Local unrest does seem to affect volumes positively, but not in any significant degrees from what I've seen, even in these extreme cases.
Hong Kong can become a very important place for crypto, and can affect its price
They can prove that Bitcoin can help with anonymity for matters involving the protests, but affecting global prices is a long shot considering their currency isn't really at risk:
The Hong Kong Monetary Authority (HKMA), the city’s de-facto central bank, buys local dollars if it gets too weak and sells to curb excessive strength.
It has plenty of firepower, with $448.5 billion of assets in its foreign exchange fund alone as of July, representing roughly seven times the currency in circulation, according to HKMA.
Getting rid of their HKD isn't a pressing matter at the moment.
